Light cruiser of the Bahia class

On 4 July 1945, Bahia was stationed in the central Atlantic, halfway between Brazil and Africa, for potential lifesaving duties for US planes in trans-Atlantic transfer to locations in Europe & the Pacific.
While conducting AA firings with her 20-mm guns against a kite streamed astern, a gunner shot the kite down and, following it on the way down, unintentionally hit a rack of depth charges on the fantail, which exploded, causing Bahia to sink within 3 minutes. The guns were not fitted with training stops to prevent them from shooting at angles where they endangered other weapon positions.
The distater was not discovered until 8 July, when sistership Rio Grande do Sul arrived at the station to relieve Bahia, by which time less than half the crew was still alive, 294 had perished.

We don't have any commands listed for BZ Bahia (C 12)
